DESCRIPTION
ENTERTAINMENT SYSTEM AND DATA SUPPLY METHOD, DATA
PROCESSOR AND METHOD OF DATA PROCESSING, DATA STORAGE
CONTROLLER AND METHOD OF DATA STORING
BACKGROUND OF THE INVENTION
Field of the Invention
This invention concerns an entertainment system and data supply method, data
processor and method, and data storage controller and method that perform
communication with external function expansion devices; in particular, the
invention
concerns an entertainment system and data supply method, data processor and
method,
and data storage controller and method that are suitable for a system that
employs a
video game machine and a nonvolatile memory card system.
Background of the Invention
A home console of a personal computer, etc., can be used with its functions
expanded by connecting general-purpose function expansion devices such as a
modem
2U or a hard disk meeting the PCMCIA (Personal Computer Memory Card
International
Association) standard. The device drivers and other software for these
function
expansion devices are normally supplied by the manufacturer of the function
expansion
device. Therefore the home console can be connected with various function
expansion
devices by causing the hard disk drive and other memory devices to hold device
drivers
for the various function expansion devices to be connected.
Meanwhile, there are conventional video game machines, such as television
game devices, as home consoles. These conventional video game machines, which
are
widely popular, allow one to play, for example, competitive games by means of
operation devices, etc., employing game data, etc. stored in, for example,
large-capacity

2
media or auxiliary memory devices and running application programs on the
video
game machine main unit.
Many of these video game machines generally have superior processing ability
for image and voice data, etc. to allow the users to experience complex and
realistic
images and sounds, etc. Specifically, by making use of their superior data
processing
capacity, video game machines available heretofore have been able, for
example, to
display the complex game characters needed for playing games as well as
express rich
sounds for a sense of presence, providing more-detailed image and sound output
than
existing computers.
Since its calculationai resources are limited, it is difficult for a
conventional
video game machine to hold device drivers, which are the control programs that
control
the aforesaid various function expansion devices, and thus it has been
impossible to
realize connection with various function expansion devices.
Because various function expansion devices are frequently being given faster
speed, larger capacity, and greater density, device drivers are supplied that
keep up with
this upgraded performance. But the problem is that device drivers must first
be held and
published in the CD-ROM and other package media by which application software
is
supplied in video games, and it is difficult to supply device drivers to keep
up with the
' technical innovations that are constantly taking place in expansion devices.
. 20 Meanwhile, personal computers, etc. hold on their disk drive, etc. the
multiple
device drivers for various function expansion devices. In a personal computer,
etc., a
single hardware resource such as a parallel communication terminal is shared
by
i
multiple device drivers. Therefore in such a system, device drivers contend
for
hardware resources, which interferes with normal operation.

(Memory card hardware layer)
Figure 3 shows the hardware layer of a memory card that the entertainment
system has.
As shown specifically in Figure 3, a memory card hardware layer 30 of memory
card 3 has a nonvolatile memory 31, which is a program data storage means in
which
program data input from video game machine 2 is held; and a microprocessor 32,
which
has the function of a data retrieval means that retrieves from device driver

which is held in nonvolatile memory 31 and is described below, a device driver
150 for
CA 02307643 2000-04-19
WO 00/11565 PCT/JP99/04486
11
performing data transmission and reception between video game machine 2 and
expansion device 5; it also has a serial communication block 33 and a buffer
34. In
memory card hardware layer 30, these parts are connected to a bus 35.
Nonvolatile memory 31 is a memory unit in which various data is stored. Stored
in this nonvolatile memory 31 is program data such as a device driver data
file 110,
which is supplied from video game machine 2 via serial communication black 33.
Also
stored in nonvolatile memory 31, besides program data, is ordinary data
supplied from
video game machine 2.
Serial communication block 33 is constituted to have the function of
performing
serial communication with external devices. The serial communication block 33
can be
connected electrically to, for example, serial communication block 23 of video
game
machine 2, thereby making it possible for memory card 3 to transmit and
receive data
with video game machine 2. Supplied to memory card 3 via this serial
communication
block 33 is device driver data file 110, etc., which is stored on a large-
capacity medium
(not shown) mounted on the video game machine 2.
Buffer 34 is a memory unit that is used as the working area for various data.
For
example, device driver data file 110 or data such as identification
information that is
supplied from video game machine 2 via serial communication block 33 is stored
temporarily in this buffer 34 before it is held in nonvolatile memory 31.
Microprocessor 32 is constituted to have the function of controlling the
aforesaid
blocks; for example, it controls the input and output of data when data is
transmitted and
received with video game machine 2. Also, microprocessor 32 retrieves the
desired
device driver 150 from device driver data file 110 held in nonvolatile memory
31, based
on the identification information of expansion device S which is connected to
video
game machine 2.
The card 3, which is formed so as to be detachable with respect to video game
machine 2, transmits and receives data from and to video game machine 2. In
entertainment system 1, whose hardware layer is thus constituted and which has
video
CA 02307643 2000-04-19
WO OO/115G5 PCT/JP99/04486
12
game machine 2 and memory card 3, data is transmitted and received between
video
game machine 2 and expansion device 5 via general-purpose interface 4.
(General-purpose interface hardware layer)
As shown in Figure 4, an interface hardware layer 40 of general-purpose
interface 4 has a general-purpose interface block 41 and a parallel
communication block
42. As also shown in Figure 4, an expansion device hardware layer SO of
expansion
device 5 has a function expansion block 51 and a general-purpose interface
block 52.
General-purpose interface 4 is constituted so as to be detachably connectable
with
parallel communication block 22 of video game machine 2 via parallel
communication
block 42 and constitutes a communication means when data is transmitted and
received
between video game machine 2 and expansion device S via general-purpose
interface
block 41. Expansion device 5 is detachably connected to general-purpose
interface
block 41 of general-purpose interface 4 via general-purpose interface block 52
and
provides the video game machine 2, via general-purpose interface 4,
identification
information for identifying the functions present in function expansion block
SI. Here
the identification information includes at least information on the type of
expansion
device 5, such as modem or hard disk, and information identifying the
specifications of
expansion device S, such as, in the case of a modem, its communication rate
and format.
(Constituent blocks of the entertainment system)
Figure 5 is a block diagram showing the configuration of the hardware layer
and
software layer of the entertainment system.
In entertainment system 1, the logical relationships when video game machine 2
and memory card 3 are connected and a device driver which allows video game
machine 2 to communicate with expansion device 5 is supplied to memory card 3
assumes the structure shown in Figure 5, and data is transmitted and received
between
video game machine 2 and memory card 3. As its hardware layer, video game
machine
2 has the video game machine hardware layer 20. As its software layer, it has
a device
driver installation software 60 for supplying to memory card 3 the device
driver 150 that
is read by CPU 21 from a large-capacity medium (not shown) mounted on large-
CA 02307643 2000-04-19
WO 00/11565 PCTIJP99/04486
I3
capacity medium block 25, and a serial communication drives 70. Here,
aforesaid serial
communication block 23 performs data transmission and reception on serial
communication driver 70. On the other hand, memory card 3 has aforesaid memory
card hardware layer 30 as its hardware layer and a serial communication driver
80 as its
software layer. Like video game machine 2, the serial communication block 33
performs data transmission and reception on serial communication driver 80.
(Series of processing steps in the video game machine)
Figure 6 is a flowchart showing a series of steps by which the video game
machine supplies device drivers and identification information to the memory
card.
In the entertainment system 1, video game machine 2 supplies device drivers
150, which make it possible to communicate with expansion device 5, to memory
card 3
by a series of steps such as shown in Figure 6.
As shown in Figure 6, in step S1, video game machine 2, by means of CPU 21,
activates device driver installation software 60 and reads device driver 150
for
expansion device 5 and identification information for identifying said
expansion device
5, which are held in the large-capacity medium mounted on large-capacity
medium
block 25.
Next, in step S2, video game machine 2, by means of CPU 21, puts read device
driver 150 and identification information in main memory 24.
Then, in step S3, video game machine 2, by means of CPU 21, opens
communication with serial communication block 33 of memory card 3 via serial
communication block 23 and establishes a communication path. The operation of
the
video game machine in step S3 corresponds to the operation of the memory card
in step
S12 of Figure 7.
Then, in step S4, video game machine 2 makes use of this established
communication path to transmit to memory card 3 the device drivers 150 and
identification information held in main memory 24. The operation of the video
game
machine in step S4 corresponds to the operation of the memory card in step S13
of
Figure 7.
CA 02307643 2000-04-19
WO 00/11565 PCT/JP99/04486
14
In order to confirm whether transmission of device drivers 150 and
identification
information has terminated, in step S5, video game machine 2 decides, by means
of
CPU 21, whether all of the device drivers 150 and identification information
in main
memory 24 have been transmitted. Here, if CPU 21 confirms that all of the
device
drivers 150 and identification information held in main memory 24 have been
transmitted, video game machine 2 terminates execution of device driver
installation
software 60 and terminates transmission processing of device drivers 150 and
identification information. If CPU 21 confirms that not all of the device
drivers 150 and
identification information held in main memory 24 have been transmitted, video
game
machine 2 again executes processing beginning with aforesaid step S4.
{Series of processing steps in the memory card)
Figure 7 is a flowchart showing a series of steps by which the video game
machine supplies the device drivers and identification information to the
memory card.
Corresponding to the processing by video game machine 2, as shown in Figure 7,
in step S11, memory card 3 decides whether there is a serial communication
connection
request from video game machine 2 and waits.
In step S11, if memory card 3 confirms that there has been a serial
communication connection request from video game machine 2, then in step S12,
by
means of microprocessor 32, it opens communication with serial communication
block
23 of video game machine 2 via serial communication block 33 and establishes a
communication path. The operation of the memory card in step S22 corresponds
to the
operation of the video game machine in step S3 of Figure 6 above.
In memory card 3, in step S13, microprocessor 32, using this established
communication path, temporarily puts into buffer 34 the device drivers 150 and
identification information received from video game machine 2, then puts it
into
nonvolatile memory 31. The operation of the memory card in step S13
corresponds to
the operation of the video game machine in step S4 of Figure 6 above.
CA 02307643 2000-04-19
WO 00/11565 PCT/JP99/04486
Here, the processing done by memory card 3 in these steps S12 and SI3
corresponds to the earlier described processing done by video game machine 2
in steps
S3 and S4, respectively.
In order to confirm whether reception of device drivers 150 and identification
5 information has terminated, in step 514, memory card 3 decides, by means of
microprocessor 32, whether all of the device drivers 150 and identification
information
from video game machine 2 have been received. Here, if microprocessor 32
confirms
that all of the device drivers 150 and identification information from video
game
machine 2 have been received, memory card 3 terminates reception processing of
10 device drivers 150 and identification information. If microprocessor 32
confirms that
not all of the device drivers 150 and identification information from video
game
machine 2 have been received, memory card 3 again executes processing
beginning
with aforesaid step S13.
The above described series of processing steps by video game machine 2 and
15 memory card 3 makes it possible in entertainment system 1 for video game
machine 2
to supply device drivers 150 and identification information to memory card 3,
and to
hold device drivers 150 and identification information in memory card 3.
With reference to Figures 9 through 12, the steps will be described until
communication is done between video game machine 2 and expansion device 5, and
with reference to Figures 8 and 13, the logical relationship between the
various
hardware at that time will be discussed.
(Configuration block of entertainment system, general-purpose interface, and
expansion
devices)
Figure 8 shows the hardware layer and software layer of the entertainment
i 25 system, a general-purpose interface, and expansion devices in the state
in which the
I
device drivers have not been read onto the video game machine.
As shown in Figure 8, video game machine 2 has, as its software block,
expansion device use application software 100, which by means of CPU 21 reads
from a
large-capacity medium (not shown) mounted on large-capacity medium block 25 in

order to perform communication with expansion device 5; serial communication
driver
70; and a parallel communication driver 90. Here, aforesaid parallel
communication
block 22 performs data transmission and reception of parallel communication
driver 90.
Memory card 3, besides the above configuration, has device driver data file
110, which
consists of multiple device driver files and identification information
supplied from
video game machine 2 and held in nonvolatile memory 31.
As shown in Figure 8, general-purpose interface 4 has as its hardware layer
the
earlier described general-purpose hardware layer 40. As its software layer it
has a
general-purpose interface communication driver 120 for performing data
transmission
and reception with expansion device S, and a parallel communication device 130
for
performing data transmission and reception with video game machine 2. Here,
the
general-purpose interface block 41 and parallel communication block 42 perform
data
,, transmission and reception on general-purpose interface communication
driver 120 and
parallel communication driver 130, respectively. Also, expansion device S has
as its
hardware layer the earlier described expansion device hardware layer 50. As
its
software layer it has general-purpose interface communication driver 140 for
' performing data transmission and reception with general-purpose interface 4.
The
general-purpose interface communication driver 140 controls the operation of
aforesaid
general-purpose interface block 52.
In the state shown in Figure 8, the video game machine 2 is able to receive
expansion device 5 identification information via general-purpose interface 4,
but
because the device driver 150 that corresponds to the expansion device 5 that
is
- connected to video game machine 2 via general-purpose interface 4 does not
exist in the
space in main memory 24, expansion device use application software 100 is
unable to
control expansion device 5.
In each hardware having the above-described structure, expansion device use
application software 100 is activated on video game machine 2, and by the
series of
processing shown in Figures 9 and 10, the device driver 150 that corresponds
to the
CA 02307643 2000-04-19
WO 00/11565 PCT/JP99/04486
17
expansion device 5 that is connected to video game machine 2 via general-
purpose
interface 4 is supplied from memory card 3 to video game machine 2.
(Series of processing steps in the video game machine)
Figure 9 is a flowchart showing a series of processing in said video game
S machine, showing the series of steps by which device drivers are supplied
from said
memory card to said video game machine.
As shown in Figure 9, in step S21, video game machine 2 reads by means of
CPU 21, via parallel communication block 22 and general-purpose interface 4,
the
identification information concerning expansion device in function expansion
block 51
of expansion device S.
In step S22, video game machine 2 puts this read identification information
into
main memory 24 by means of CPU 21.
Next, in step S23, video game machine 2, by means of CPU 21, opens
communication with serial communication block 33 of memory card 3 via serial
communication block 23, and establishes a communication path. The operation of
the
video game machine in step S23 corresponds to the operation of the memory card
in
step S42 of Figure 10 below.
In step S24, using this established communication path, in video game machine
2, CPU 21 makes a request to memory card 3 to transmit the device driver file
that
corresponds to the device driver 150 that corresponds to the identification
information
-- held in main, memory 24. The operation of the video game machine in step
S24
corresponds to the operation of the memory card in step S43 of Figure 10
below, and an
exchange arises between the two.
In the following step S25, the series of processing is terminated if the
device
driver file requested by video game machine 2 does not exist on memory card 3.
On the
other hand, if the device driver tile requested by video game machine 2 does
exist on
memory card 3, it proceeds to the following step S26, and video game machine
2, using
the communication path established with memory card 3, receives the device
driver file
by means of CPU 21 and puts it into main memory 24 as device driver 150. The
CA 02307643 2000-04-19
WO 00/11565 PCT/JP99/04486
18
operation of the video game machine in step S26 arises from the operation of
the
memory card in step S45 of Figure 10 described below.
In step S27, in order to confirm termination of receipt of the device driver
file
from memory card 3, video game machine 2 decides by means of CPU 21 whether
all
the data has been received. Here, if CPU 21 confirms that all of the device
driver file
has been received from memory card 3, video game machine 2 terminates
reception
processing. And if CPU 21 confirms that not all of the device driver file has
been
received from memory card 3, video game machine 2 again executes processing
from
aforesaid step S26.
(Series of processing steps in the memory card)
Figure 10 is a flowchart showing a series of processing steps in the memory
card,
where the device drivers are supplied from the memory card to the video game
machine.
Corresponding to such processing by video game machine 2, as shown in Figure
10, in step S41, memory card 3 decides whether there is a serial communication
connection request from video game machine 2 and waits.
In step S41, if it confirms that there has been a serial communication
connection
request from video game machine 2, then in step S42, by means of
microprocessor 32, it
opens communication with serial communication block 23 of video game machine 2
via
serial communication block 33 and establishes a communication path. The
operation of
the memory card in step S42 corresponds to the operation of the video game
machine in
step S23 of Figure 9 above.
-= In memory card 3, in step S43, microprocessor 32 retrieves the device
driver file
requested by video game machine 2 from within device driver file 210, which
consists
of multiple device driver files and identification information held in
nonvolatile
memory 31, and replies to video game machine 2 whether this file exists. The
operation
of the memory card in step S43 corresponds to the operation of the video game
machine
in step S24 of Figure 9 above, and an exchange takes place between the two.
In Lhe following step S44, the series of processing is terminated if the
device
driver file requested from video game machine 2 does not exist within device
driver
CA 02307643 2000-04-19
WO 00/11565 PCT/JP99/04486
19
data file 110. On the other hand, if the device driver file does exist within
device driver
data file 110, it proceeds to the following step S45, and memory card 3, by
means of
microprocessor 32, reads the device driver file requested by video game
machine 2 from
nonvolatile memory 31 and transmits this device driver file to video game
machine 2
using the communication path that has been established with video game machine
2.
The operation of the memory card in step S45 leads to the operation of the
video game
machine in step S26 of Figure 9 above.
The processing done by memory card 3 in these steps S42, S43, and S45
corresponds to the above-described processing done by video game machine 2 in
steps
S23, S24, and S26, respectively.
In step S26 memory card 3 decides by means of microprocessor 32 whether all
of the device driver file has been transmitted to video game machine 2. If
microprocessor 32 confirms that all of the device driver file has been
transmitted,
memory card 3 terminates transmission processing. And if microprocessor 32
confirms
that not all of the device driver file has been transmitted, memory card 3
again executes
processing from aforesaid step S45.
The aforesaid series of processing makes it possible in entertainment system 1
to
retrieve, from within device driver data file 210 held in nonvolatile memory
31 of
memory card 3, what corresponds to the identification information of expansion
device
5 and transmit it to video game machine 2.
(Series of processing steps in the video game machine)
As shown in Figure 11, in step S28, by means of CPU 21, video game machine 2,
which has received the device driver file corresponding to expansion device 5,
allocates
this device driver file to a location in main memory 24 that can be called
from
expansion device use application software 100, and rewrites the various
reference tables
stored in main memory 24 so that it can be called from expansion device use
application
software 100.
In step S29, in video game machine 2, CPU 21 opens communication with
function expansion block 51 of expansion device 5 via parallel communication
block 22
CA 02307643 2000-04-19
WO 00/11565 PCT/JP99/04486
and general-purpose interface 4 of video game machine 2 and general-purpose
interface
blocks 41 and 52 of expansion device 5, and establishes a communication path.
The
operation of the video game machine in step S29 corresponds to the operation
of the
expansion device in step S52 in Figure 12 described below.
S Video game machine 2, as in step S30, by means of CPU 21, according to the
instructions of expansion device use application software 100 and using the
established
communication path, controls expansion device 5 and performs data transmission
and
reception. The operation of the video game machine in step S30 corresponds to
the
operation of the expansion device in step S53 in Figure 12 below.
10 (Series of processing steps in the expansion device)
Figure 12 is a flowchart showing a series of processing in the expansion
devices,
showing the steps until communication takes place with the expansion devices,
using
the device drivers that are supplied from the memory card to the video game
machine.
Corresponding to this processing by video game machine 2, as shown in Figure
15 12, in step SS1, expansion device S decides whether there is a connection
request from
video game machine 2 and waits.
In this step S51, if it is confirmed that there has been a connection request
from
video game machine 2, then in step S52 expansion device S begins communication
with
function expansion block 51 and parallel communication block 22 of video game
20 machine 2 via general-purpose interface blocks 52 and 41 of expansion
device 5 and
general-purpose interface 4, and establishes a communication path. The
operation of
the expansion device in step S52 corresponds to the operation of the video
game
machine in step S29 in Figure 11.
As in step S53, the expansion device operates in accordance with the control
instructions of expansion device use application software 100 received from
video game
machine 2 using the established communication path, and performs transmission
and
reception of data with video game machine 2. The operation of the expansion
device in
step S53 corresponds to the operation of the video game machine in step S30 in
Figure
I1.
CA 02307643 2000-04-19
WO 00/11565 PCT/JP99/04486
21
The processing done by expansion device 5 in steps S52 and S53 correspond to
the above-described processing done by video game machine 2 in steps S29 and
S30,
respectively.
(Configuration block of entertainment system, general-purpose interface, and
expansion
S device)
Figure 13 shows configuration of the hardware layer and software layer of the
entertainment system, a general-purpose interface, and expansion devices, in
the state in
which device drivers have been read onto the video game machine.
In connection with the above series of processing, the logical relationship of
each hardware changes as shown in Figure 13. That is, the structure of memory
card 3,
general-purpose interface 4, and expansion device 5 each remain unchanged, but
in
video game machine 2, the structure in which device drivers 150 are held in a
state
linked logically with expansion device use application software 100 is assumed
in the
space of main memory 24. In entertainment system 1, it is possible to load
into main
memory 24 and use only the necessary device drivers 150, as for example in a
DLL
(Dynamic Linking Library) on a personal computer. By device driver 150 being
read
into main memory 24, device driver 150 can exchange data with parallel
communication driver 90 and expansion device use application software 100.
Therefore
in entertainment system 1 it is possible for expansion device use application
software
100 to control expansion device 5 via general-purpose interface 4.
As has been explained above, in entertainment system I, by reading in from a
large-capacity medium (not shown) the device driver 150 that corresponds to
expansion
device 5 and holding it on memory card 3, mutual connection and communication
can
be made with many types of expansion devices 5, even in a video game machine 2
that
has few computation resources.
i In entertainment system 1, by holding multiple device drivers in a single
memory card 3, it suffices to use the same memory card 3 even when mutually
connecting multiple expansion devices 5 to the video game machine 2.
CA 02307643 2000-04-19
WO 00/11565 PCT/JP99/04486
22
Moreover, in entertainment system 1, it is possible to use the same
application
software for many types of expansion devices 5. That is, in entertainment
system 1 it is
possible, for example, for Internet browser software to use multiple modems of
different
speeds.
Also, in entertainment system 1, since for example one device driver 150 only
is
supplied to one hardware resource such as parallel communication block 22 on
video
game machine 2. Therefore in entertainment system 1, without hardware
resources
being shared by multiple device drivers, video game machine 2 does not
misoperate due
to the contention of a single hardware resource being acquired by multiple
device
drivers.
In entertainment system 1, by device drivers 150 being put into memory card 3
beforehand, one is spared the trouble of installing a device driver 150 in
main memory
24 every time expansion device use application software 100 is activated on
video game
machine 2.
Also in entertainment system 1, since video game machine 2 can be connected
with general-purpose interface 4, various expansion devices can be used other
than
expansion devices 5 manufactured for video game machine 2. Therefore in
entertainment system l, the function expansion of video game machine 2 can be
made
various and broad.
This invention is not limited to the embodiment described above. In video game
_. machine 2 it is not necessary to store the device drivers 150 and
identification
information to be supplied to memory card 3 on a large-capacity medium such as
a CD-
ROM; this may be acquired by, for example, communication with an external
source.
Also, in the description, the device driver corresponding to the
identification
information of expansion device 5 is retrieved by means of microprocessor 32
from a
device driver data file 110 held in memory card 3, but as entertainment system
1 one
may have a configuration in which CPU 21 of video game machine 2 is given the
function of a retrieval means and the retrieval is done by CPU 21.

[Specific applications to entertainment systems
Using Figures 14 through 18, a specific example of the entertainment system 1,
is shown. In Figures 14 through 18, video game machine 2 and memory card 3,
which
include the above-described entertainment system 1, are constituted as an
entertainment
S system consisting of a video game device 301, a portable electronic device
400, and a
memory card device 500.
The video game machine 2 corresponds to video game device 301, and memory
card 3 corresponds to memory card device 500. Specifically, with regard to the
correspondence between video game machine 2 and video game device 301, CPU 21,
parallel communication block 22, serial communication block 23, main memory
24, and
large-capacity medium block 25 of above-described video game machine 2
correspond
respectively to a CPU 351, a parallel I/O interface (PIO) 396, memory card
insertion
units 308A and 308B, a main memory 353, and an optical disk control unit 380
of video
game device 301 shown in Figure 17.
As shown in Figures 14 and 15, video game device 301 is for reading
application programs stored on a large-capacity medium and executing them in
accordance with instructions from users (game players). Here, to execute a
game means
mainly, for example, to control the progress, display, and sounds of the game.
Main unit 302 of video game device 301 is housed in a roughly rectangular
cabinet and has disk mounting unit 303, in the middle of which is mounted an
optical
disk of a CD-ROM, etc., which is a large-capacity medium for supplying video
game
and other application programs; set switch 304 for arbitrarily resetting the
video game;
power switch 305; disk operation switch 306 for operating said optical disk;
and two
i slots 307A and 307B.
Also, video game device 301 is constructed so that not only application
programs are supplied from a large-capacity medium but also so that they are
supplied
via a communication circuit.

- A portable electronic device 400 and a controller 320 can be connected to
slots
307A and 3078. In addition, a memory card device 500 can also be connected to
slots
307A and 3078.
Controller 320 has ftrst and second operation units 321 and 322; a left button
323 L; a right button 323 R; a start button 324; a selection button 325;
analog-operable
operation units 331 and 332; a mode selection switch 333, which selects the
operation
mode of operation units 331 and 332; and a display unit 334 for displaying the
selected
operation mode. Also, built into controller 320 is a vibration-causing
mechanism (not
shown). This vibration-causing mechanism causes controller 320 to vibrate in
accordance with, for example, the progress of the video game. Controller 320
is
electrically connected to slot 3078 of main unit 302 by connection unit 326.
For example by connecting two controllers 320 to slots 307A and 3078, two
players can share this entertainment system; that is, for example, competitive
games can
be played. Also, slots 307A and 3078 are not thereby limited to two systems.
As shown in Figures 16A through 16C, portable electronic device 400 is
constructed so as to have a housing 401, and it is equipped with an operation
unit 420
for input of various information; a display unit 430, which consists of, for
example, a
liquid crystal display (LCD); and a window unit 440 for performing wireless
communication by means of wireless communication means 448, for example, by
infrared rays.
Housing 401, which consists of an upper shell 401a and a lower shell 401b,
house inside it a circuit board containing memory elements, etc. The housing
401 is
shaped so as to be insertable into slots 307A and 3078 of main unit 302 of
video game
device 301.
Window unit 440 is provided on the other end of housing 401, which has a
roughly semicircular shape. Display unit 430 occupies roughly half the area of
upper
shell 401a, which makes up part of housing 401, and is provided in a position
near
window unit 440.
CA 02307643 2000-04-19
WO 00/11565 PCT/JP99/04486
Like window unit 440, operation unit 420, which has one or more operation
elements 421, 422 for performing various event input and making selections, is
formed
on upper shell 401a and occupies roughly half its area opposite window unit
440. The
operation unit 420 is constructed on cover member 410, which is supported
rotatably
5 with respect to housing 401. Here, operation elements 421, 422 are arranged
extending
from the upper surface side to the lower surface side of this cover member 410
and go
through this cover member 410. Also, operation elements 421, 422 are supported
by
cover member 410, which is made to be movable in the emerging-submerging
direction
with respect to the top surface part of cover member 410.
10 Portable electronic device 400, which is inside housing 401, has a circuit
board
positioned opposite the position in which cover member 410 is arranged, and
has on this
circuit board a switch pressing unit. The switch pressing unit is provided in
a position
that corresponds to operation elements 421, 422 when cover member 410 is
closed.
Thus when operation elements 421, 422 are pressed, the switch pressing unit
presses a
15 pressure switch such as a diaphragm switch.
As shown in Figure 15, portable electronic device 400, in which operation unit
420, etc. is thus formed in cover member 410, is mounted in main unit 302 of
video
game device 301 in the condition in which cover member 410 is open.
The circuit construction of video game device 301 and portable electronic
device
20 400 is constituted as shown in Figure 17 and Figure 18.
As shown in Figure 17, video game device 301 has a control system 350, which
includes a central processing unit (CPU) 351 and its peripheral devices; a
graphic
system 360, which includes a graphic processing unit (GPU) 362, which draws to
a
frame buffer 363; a sound system 370, which includes a sound processing unit
(SPU),
25 which generates music and sound effects; optical disk controller 380, which
controls an
optical disk on which application programs are stored; a communication
controller 390,
which controls the input and outputs signals from controller 320, to which
instructions
from users are input, and of data from memory card device 500, which stores
game
settings, etc., and portable electronic device 400; a bus 395, to which the
above-
CA 02307643 2000-04-19
WO 00/11565 PCT/JP99/04486
26
described parts are connected; and parallel I/O interface (PIO) 396 and serial
I/O
interface (SIO) 397, which constitute interfaces with other devices.
Control system 350 has CPU 351; a peripheral device controller 352, which
controls direct memory access (DMA) transfers; a main memory 353, which
consists of
S random access memory (RAM); and a read only memory (ROM) 354 in which are
', stored programs such as the so-called operating system, which manages main
memory
353, the graphic system 360, the sound system 370, etc.
CPU 351 controls all of this video game device 301 by executing the operating
system stored in ROM 354.
For example, in this video game device 301, when the power is turned on, CPU
351 of control system 350 executes the operating system stored in ROM 354, and
thereby CPU 351 controls graphic system 360, sound system 370, etc. For
example,
when the operating system is executed, CPU 351 initiates all of video game
device 301,
including confirmation of operation, then controls optical disk controller 380
and
executes the application program stored on the optical disk. By execution of
this
application program, CPU 351, in accordance with input from the users,
controls
graphic system 360, sound system 370, etc. and controls the display of images
and the
generation of sound effects and music.
CPU 351 corresponds to CPU 21 in the above-described video game machine 2;
that is, it performs restoration processing on the data received and
transmitted by
portable electronic device 400.
Graphic system 360 has, for example, the function of graphic processor 15 of
the
above-described video game machine 2. This graphic system 360 has geometry
transfer
engine (GTE) 362, which does processing such as coordinate transformations;
GPU 362,
j 25 which draws in accordance with drawing instructions from CPU 351; frame
buffer 363,
which stores images drawn by this GPU 362; and image decoder 364, which
decodes
image data compressed and encoded by orthogonal transformations such as
discrete
cosine transformations.
CA 02307643 2000-04-19
WO 00/tY565 PCT/JP99/04486
27
GTE 361 has, for example, a parallel computation mechanism that executes
multiple operations in parallel, and is able to perform at high speed such
calculations as
coordinate transforms, light source calculations, and matrix or vector
calculations in
response to calculation requests from CPU 351. Specifically, in the case of
operations
in which flat shading is done, in which, for example, a single-triangle
polygon is drawn
with the same color, this GTE 361 is able to perform coordinate calculations
for up to
about 1.5 million polygons per second, thereby both reducing the burden on CPU
351
and performing high-speed coordinate operations by this video game device 301.
GPU 362 draws polygons, etc. to frame buffer 363 in accordance with drawing
instructions from CPU 351. The GPU 362 is able to draw up to about 360,000
polygons
per second.
Frame buffer 363, which consists of so-called dual-port RAM, is able to
simultaneously carry out drawing from GPU 362 or transfers from main memory
353,
and reading for the sake of display. This frame buffer 363 has a capacity of,
for
example, 1 megabyte and can handle a matrix consisting of 1024 pixels
horizontally and
512 pixels vertically, each pixel being 16 bits.
The frame buffer 363 has, besides a display region that is output as video
output,
', a CLUT region in which is stored a color look-up table (CLUT) that is
referred to when
GPU 362 draws polygons, etc., and a texture region in which is stored the
texture that is
coordinate-transformed and mapped into polygons, etc. drawn by GPU 362 when
drawing is done. These CLUT and texture regions dynamically change as the
display
region changes.
Image decoder 364 decodes the image data of still pictures or moving pictures
stored in main memory 353 and stores the result into main memory 353, under
control
from CPU 351. The image data generated here can be used as background for
images
drawn by GPU 362, by storing it into frame buffer 363 via GPU 362.
Sound system 370 has a SPU 371, which generates music and sound effects
based upon instructions from CPU 351; a sound buffer 372, in which waveform
data,
CA 02307643 2000-04-19
WO 00/11565 PCT/JP99/04486
28
etc. is stored by SPU 371; and a speaker 373, which outputs the music and
sound effects
generated by SPU 371.
SPU 371 has, for example, an ADPCM (adaptive differential PCM) decoding
function, which generates audio data in which 16-bit audio data is adaptively
encoded as
4-bit difference signals; a playback function that plays back sound effects,
etc. by
playing back the waveform data stored in sound buffer 372; and a modulation
function,
which modulates and plays back the waveforrn data stored in sound buffer 372.
Sound system 370 can be used as a so-called sampling sound source, which
generates music and sound effects based on waveform data stored in sound
buffer 372
under instructions from CPU 351.
Optical disk controller 380 has an optical disk device 381, which plays back
the
application programs and data, etc. stored on a CD-ROM or other optical disk;
a
decoder 382, which decodes programs and data, etc. that have been stored, for
example,
with an added error correction code (ECC); and a buffer 383, which speeds up
the
reading of data from the optical disk by temporarily storing data from optical
disk
device 381. A sub-CPU 384 is connected to decoder 382.
As audio data read by optical disk device 381 and stored on optical disk,
there is,
besides the above-described AI7PCM data, so-called PCM data, in which an
analog/digital transformation is performed on audio signals. As an example of
ADPCM

communication with many kinds of function expansion devices can be done, even
in a
data processing device having limited calculation resources, and by holding
control
programs beforehand in the secondary memory, one is spared the trouble of
installing
S the control program in the main memory means every time an application
program that
uses a function expansion device is to be used on the data processing device.
Also, in the entertainment system of this invention, the secondary memory has
a
data storage means in which are held the control programs and identification
information supplied from the data processing device, and held in this data
storage
means are multiple control programs and identification information
corresponding to
multiple function expansion devices.
In the entertainment system of this invention, by holding multiple control
programs and identification information in a single secondary memory, the same
secondary memory can be used even when multiple function expansion devices are
to
be connected together and used in the data processing device.

corresponds to the identification information from the function expansion
devices,
In the entertainment system of this invention, because control programs are
selected based on the identification information, only a single control
program is
supplied to a single hardware resource of the data processing device.
Therefore without
hardware resources being shared by multiple control programs, the data
processing
device does not misoperate due to the contention of a single hardware resource
being
acquired by multiple control programs.
The data supply method of the invention is a data supply method in which a
secondary memory is detachably connected to, and performs data transmission
and
reception with respect to, a data processing device, and control programs that

programs, the
data processing device does not misoperate due to the contention of a single
hardware
resource being acquired by multiple control programs.
Also, in the data supply method of this invention, by holding control programs
beforehand in the secondary memory, one is spared the trouble of installing
the control

programs
and identification information supplied by this data supply means; and a main
memory
means in which control programs and identification information are stored.
In the data processor of this invention, by supplying to and holding in the
secondary memory the control programs and identification information, it is
possible to
mutually connect and communicate with many types of function expansion

which data processing is done with the secondary memory connected detachably;
control programs that control externally provided function expansion devices
are
supplied, these control programs are supplied to and held in the secondary
memory, and
control programs corresponding to the connected function expansion devices are
retrieved from among the control programs held in the secondary memory and are
stored.

mutually
connect and communicate with many types of function expansion devices, even
with
limited calculation resources.
In the data processing method of this invention, because a single control
program is supplied from the secondary memory, only a single program is
supplied to a
single hardware resource. Therefore without hardware resources being shared by

programs that
control externally provided function expansion devices and identification
information
that identifies the function expansion devices, and multiple control programs
that
correspond to multiple function expansion devices as well as identification
information
10 are held in the data storage means.

communication with many kinds of function expansion devices can be done, even
in a
data processing device having limited calculation resources, and by holding
multiple
programs, it can be used even when multiple function expansion devices are to
be
15 mutually connected to the data processing device. And by holding control
programs
beforehand, there is no longer any need to install the control program every
time an
application program is started in which the data processing device uses a
function
expansion device.
Also, the data storage controller of this invention has a data retrieval means
that
20 retrieves from among the control programs held in the data storage means
the control
programs that correspond to the function expansion devices, retrieves control
programs
corresponding to the function expansion devices by this data retrieval means
from
i
among the control programs stored in the data storage means, and supplies
these control
programs to the data processing device.

Thus, in the data storage control method of this invention, mutual connection
and communication with many kinds of function expansion devices can be done,
even
in a data processing device having limited calculation resources, and by
holding control
programs beforehand, one is spared the trouble of installing a control program
on the
data processing device every time an application program is started that uses
a function
